First thing is what are you shooting them in? I've always heard that ribbed shells are sticky in a double but if they're for a 97 no problem. In my opinion, for regular smokeless powder, clays-red dot etc, WW AAs are the easiest to reload, they are slick and reload nicely. As far as using black I can't tell you which is the best hull or wad. Plastic wads and black powder will coat your bores with nasty, don't ask me how I know. Good luck. Have fun. Stay safe.
